This post is an answer to the ECG Case 268
- Rate: 66 bpm
- Rhythm: Regular, sinus rhythm
- Axis: Normal
- Intervals:
- PR – Normal (~180ms)
- QRS – Normal (80-100ms)
- QT – 480ms
- Segments:
- ST depression in leads I, V2-6
- Subtle ST elevation in lead V1
- Additional:
- High precordial R wave voltages
- Deep T wave inversion in leads V2-3
- Global T wave inversion – all leads except aVR
Interpretation
Apical Hypertrophic Cardiomyopathy (Deep T wave inversion, high R wave voltages, QT prolongation)
This patient had known hypertrophic apical cardiomyopathy with diastolic dysfunction but preserved systolic function.
